A handy built-in compartment on the post is perfect for storing flat newspapers and magazines, along with packages. In addition, a rear door on the mailbox keeps children and adults safely away from traffic. The Gentry installs over an existing 4×4 post (sold separately) and features a five-year limited warranty.
